fraction equation out of the fraction line

Question

I'm using an overleaf springer nature latex template. It can be found here: I tried many packages to get this equation to appear right without success. It appears like . If I use the Elsevier latex template overleaf or online equation editor the equation will appear just fine. Any help, please.

\documentclass[default,iicol]{sn-jnl}% Default with double column layout
\jyear{2021}%
%% as per the requirement new theorem styles can be included as shown below
\theoremstyle{thmstyleone}%
\newtheorem{theorem}{Theorem}%  meant for continuous numbers
%%\newtheorem{theorem}{Theorem}[section]% meant for sectionwise numbers
%% optional argument [theorem] produces theorem numbering sequence instead of independent numbers for Proposition
\newtheorem{proposition}[theorem]{Proposition}% 
%%\newtheorem{proposition}{Proposition}% to get separate numbers for theorem and proposition etc.
\theoremstyle{thmstyletwo}%
\newtheorem{example}{Example}%
\newtheorem{remark}{Remark}%
\theoremstyle{thmstylethree}%
\newtheorem{definition}{Definition}%
\raggedbottom
%%\unnumbered% uncomment this for unnumbered level heads
\begin{document}
\section{Equations}\label{sec1}
% EQUATION 1
\begin{equation}
\label{Eq.1}
P(h(x)|S) = \frac{P(h(x) \cdot P(S|h(x))}{P(S)}
\end{equation}
\end{document}

Welcome to tex.sx. I haven't tested this, but it looks like there are more opening parentheses than closing ones. Count them carefully to make sure they match, and try again. — barbara beeton, May 23 '22 at 00:27

consider @Barbara Beeton comment, and
instead of | you had to use the \mid:

\documentclass[default,iicol]{sn-jnl}% Default with double column layout
\jyear{2021}%
\begin{document}
\section{Equations}
\label{sec1}
\begin{equation}\label{Eq.1}
P(h(x)\mid S) = \frac{P(h(x)) \cdot P(S\mid h(x))}{P(S)} %, 
\end{equation}
\end{document}

+1: Nice find! :). Related: https://tex.stackexchange.com/questions/52901 – Dr. Manuel Kuehner May 23 '22 at 03:05
Regarding Barbara's comment: I did not see unbalanced brackets. – Dr. Manuel Kuehner May 23 '22 at 03:06

@Dr.ManuelKuehner, She is right. Instead P(h(x) \cdot ... should be P(h(x)) \cdot ...) – Zarko May 23 '22 at 03:10
Ah, I see, but I did not think that this is related to the problem. Thanks for the reply. – Dr. Manuel Kuehner May 23 '22 at 03:11

@Dr.ManuelKuehner, apparently contributed. Without closed parenthesis I get error: missing $. It seems that sn-jnl is more pedantic and picky as article :-) – Zarko May 23 '22 at 03:15

Works for me?! Please provide a complete code example, see here.

\documentclass{article}
\begin{document}
\begin{equation} 
P(h(x)|S) = \frac{P(h(x) \cdot P(S|h(x))}{P(S)}
\label{Eq.1}
\end{equation}
\end{document}

@AbdullaAburomman I recommend that you provide a compilable code example and include it in your question. That makes things much easier for others to help (less guesswork). The linked template seems complex - so please boil it down to the essentials regarding the problem. – Dr. Manuel Kuehner May 23 '22 at 01:05
"I recommend that you provide a compilable code example and include it in your question". I did that by re-editing my post. – Abdulla Aburomman May 23 '22 at 13:27
Thank you very much, your solution works. :-) – Abdulla Aburomman May 23 '22 at 13:57
